The Conair Travel Smart Adapter Combo provides everything you need in an international power converter: it's lightweight, small, self-contained, capable of operating in most countries, and protects you against power surges. Also, it's pretty cheap.

For all those reasons (and a few more), best buys blog The Wirecutter named it their favorite international power adapter. Here's why:

At $23,The Conair Travel Smart Adapter Combo with Surge Protection is cheap enough to own more than one of. It offers four different plug configurations, that'll allow you to plug it into the wall in over 150 different countries. It can run in two different modes: adapter only and adapter/convert, making it possible power your 110/120v volt hardware, even if the current coming out of the wall is 220/240v. Better still, the Conair also boasts a built-in surge protector-a nice feature to have for anyone visiting underdeveloped countries where power surges are common. Most importantly, weighing in at seven ounces and 4.2 x 2.5 x 6.2 inches, it's small and light. You want that. After all, the stuff you need to make your hardware work shouldn't weigh more than the hardware itself.

It's hard to disagree. While it may not be the prettiest plug you'll ever lay eyes on, it's hard to find something more portable, functional, and self-contained. If you're traveling internationally, this is the adapter you want to get.
